If you have ever found yourself browsing the "sexual wellness" aisle—either virtually or in person—you know the struggle. You want a solution that helps you (or your partner) last longer, but the options feel like a confusing mix of medical textbooks and questionable marketing. Two names always float to the top: Promescent and Stud 100.
They are the titans of the delay spray world. Promescent markets itself as the high-tech, dermatologist-developed premium option, while Stud 100 is the heritage brand that has been in nightstands since the 1970s. But when you are trying to calculate the value, it gets tricky. Is the cheaper bottle actually a better deal? Or are you paying for "cheap" with a lack of sensation?
In this guide, we are breaking down the Cost Per Use of these two heavy hitters. We will analyze the math, the sensation, and the hidden "numbness tax" that many couples forget to factor in. Plus, we will share why we ultimately moved away from lidocaine-based sprays entirely in favor of a plant-based alternative that changed the game for us.
Quick Summary: The "Bottom Line Up Front"
Don't have time to do the math? Here is the cheat sheet on which spray fits your needs:
- Best Budget Pick (Stud 100): If you need volume on a shoestring budget, Stud 100 wins on price per spray (~$0.11). However, be warned: it uses a heavy lidocaine dose that can risk numbing both partners if not applied carefully.
- Best "Tech" Pick (Promescent): If you have a higher budget, Promescent's "TargetZone" technology absorbs better than Stud 100, minimizing transfer. But at ~$1.00+ per spray, it is a significant investment for every session.
- Our Top Pick (Bombex Phyto Delay Spray): For couples who hate the "medical" smell and numbing effect of lidocaine, Bombex is the superior choice. It uses plant-based extracts to reduce over-sensitivity without killing the mood or sensation.
The Cost Per Use Analysis: Doing the Math
When you buy a delay spray, you aren't just buying a bottle; you are buying "sessions." To truly understand the value, we need to look at the cost per spray and the typical dosage required to get results.
Stud 100: The Volume King
Stud 100 is famous for being affordable. A standard bottle contains about 12g (roughly 7/16 fl oz) of fluid. The manufacturer claims this yields approximately 120 sprays.
- Average Price: ~$13.00 - $15.00
- Total Sprays: ~120
- Cost Per Spray: ~$0.11
- Typical Dosage: 3–8 sprays per session.
- Cost Per Session (Avg 5 sprays): $0.55
The Verdict: Strictly mathematically, Stud 100 is incredibly cheap. However, users often report needing more sprays to get the desired effect, and the nozzle mechanism is less precise than modern competitors.
Promescent: The Premium Investment
Promescent positions itself as a medical-grade solution. Their standard bottle is significantly smaller in volume compared to Stud 100, but they claim their formula is more potent due to absorption technology.
- Average Price (Standard Bottle): ~$23.00 (Trial/Small) to ~$60.00 (Standard)
- Total Sprays: ~20 (Small) to ~60 (Standard)
- Cost Per Spray: ~$1.00
- Typical Dosage: 3–5 sprays per session.
- Cost Per Session (Avg 4 sprays): $4.00
The Verdict: Promescent is roughly 10x more expensive per spray than Stud 100. While the technology is better, adding a $4 surcharge to every intimate encounter is a steep ask for many couples.
The "Hidden Cost" of Lidocaine
Here is the factor that spreadsheets don't show: Sensation Loss. Both Promescent and Stud 100 rely on Lidocaine. Lidocaine is a topical anesthetic—the same stuff dentists use to numb your gums. While effective at stopping premature ejaculation (PE), it works by deadening the nerves.
The "cost" isn't just money. If you use too much Stud 100 to save cash, you risk "numbing out" completely, leading to loss of erection (ED). If you use Promescent, you pay a premium to reduce that risk, but you are still applying a numbing agent to your most sensitive area.
Product Spotlight: Why We Switched to Bombex
After testing the market, we found that the best balance wasn't about finding the cheapest lidocaine; it was about ditching lidocaine entirely. This is why we recommend the Bombex Phyto Delay Spray For Men.
Instead of freezing your nerves, Bombex uses a proprietary blend of plant-based herbal ingredients. This approach "mellows" the nerve response rather than blocking it. You still feel the warmth, the texture, and the pleasure—you just don't get the overwhelming spike of sensation that triggers an early finish.
Feature Comparison
| Feature | Stud 100 | Promescent | Bombex Phyto Spray |
|---|---|---|---|
| Active Ingredient | Lidocaine (9.6%) | Lidocaine (10%) | Plant-Based Extracts |
| Sensation | Numbing (High risk) | Reduced Sensitivity | Natural Feeling |
| Transfer Risk | High (Must wash off) | Low (If dried) | Minimal (Fast Absorb) |
| Odor | Medical/Chemical | Slight Chemical | Gentle Herbal |
Detailed Guide: How to Use Delay Spray for Maximum Effect
Buying the spray is only step one. The biggest reason men say these products "don't work" is incorrect application. Whether you are using the Bombex Phyto Delay Spray For Men or a lidocaine alternative, the technique matters as much as the formula. Here is a step-by-step breakdown on how to incorporate spray into your foreplay routine seamlessly.
1. The "Dry Dock" Application
Never apply delay spray to wet skin. Moisture creates a barrier that prevents the active ingredients—whether herbal or anesthetic—from penetrating the epidermis effectively. Before you start anything, dry the area gently with a towel. This ensures the product absorbs into the nerve endings rather than sliding off onto your sheets.
2. Target the "Hot Zones"
You do not need to spray the entire shaft like you are applying sunscreen. Focusing on the specific areas of highest sensitivity will give you better control with less product.
- The Frenulum: This is the small ridge of skin on the underside of the glans (head) where it connects to the shaft. For most men, this is the "trigger point" for ejaculation. One directed spray here is often worth three sprays elsewhere.
- The Glans (Head): The underside of the head is generally more sensitive than the top. Apply one spray here and use a finger to rub it in a circular motion until it is fully absorbed.
3. The "Wait and Marinate" Rule
This is where patience pays off. If you spray and immediately insert, you will transfer the product to your partner (numbing them) and it won't have time to work on you. You must wait at least 10 to 15 minutes.
Pro Tip: Use this time for foreplay that doesn't involve the penis. Focus on oral sex for her, massage, or manual stimulation. This keeps the mood high while the spray does its job.
Recommended Positions for Stamina
Combining a delay spray with the right physical positioning is the ultimate hack for longevity. Here are three positions that work synergistically with desensitizing sprays:
The Coital Alignment Technique (CAT)
This is a variation of missionary that focuses on grinding rather than thrusting. By keeping your bodies flat against each other and using a rocking motion, you stimulate the clitoris intensely (good for her) while reducing the piston-like friction on the penis shaft (good for you). The Bombex spray helps manage the sensitivity of the contact, allowing you to maintain this rhythm for much longer.
Spooning (Side-Lying)
Lying on your sides with your partner facing away from you allows for shallower penetration. This reduces the stimulation on the cervix and the deep thrusting that often pushes men over the edge too quickly. It is an intimate, high-contact position that allows you to take breaks easily without breaking physical connection.
The "Tabletop"
Have your partner sit on the edge of a sturdy table or counter while you stand. This allows you to control the depth and speed of thrusting completely. Standing up also changes blood flow dynamics for some men, which can naturally help delay the urge to ejaculate.
Critical Safety & Hygiene: What You Need to Know
Sexual wellness isn't just about pleasure; it's about safety. When introducing chemical or herbal agents into the bedroom, you need to be aware of how they interact with your body and your other supplies.
Lube Compatibility
If you are using a delay spray, you will almost certainly need lubricant. Delay sprays dry on the skin, and once you are ready for intercourse, you want to reduce friction to prevent irritation.
- Water-Based Lube: This is the universal donor of the sex world. It is safe to use with silicone toys, safe for latex condoms, and washes off easily. We highly recommend using a high-quality water-based lube with any delay spray.
- Silicone-Based Lube: While slick and long-lasting, silicone lube can degrade silicone toys. If you are using the Bombex spray alongside a toy, stick to water-based options to protect your investment.
- Oil-Based Lube: Avoid this with condoms. Oils (like coconut oil or massage oil) can disintegrate latex condoms in minutes, leading to breakage and potential STI transmission or unintended pregnancy.
Cleaning and Oral Safety
One of the biggest complaints about lidocaine sprays is the taste. If you don't wash it off, oral sex can be a bitter, numbing experience for your partner—literally numbing their tongue. This is a major mood killer.
The Protocol: Apply the spray, wait the full absorption time (10-15 mins), and then wash your penis with mild soap and water before engaging in oral sex. Because the product has already absorbed into the skin, washing the surface won't reduce the effect for you, but it will save your partner's taste buds.
The Phyto Advantage: This is another area where the Bombex Phyto Delay Spray shines. Because it lacks the harsh chemical bitterness of concentrated lidocaine, it is much more partner-friendly if you transition from intercourse to oral play, though we still recommend a quick rinse for the best experience.
Sensitivity and Skin Reactions
According to medical sources like the Mayo Clinic, topical anesthetics can cause contact dermatitis in some users. If you see redness, itching, or swelling, stop using the product immediately. This is often a reaction to the lidocaine itself or the preservatives in the bottle. Plant-based options can be gentler, but it is always smart to do a "patch test" on your arm before applying any new product to your genitals.
Frequently Asked Questions (FAQ)
Does delay spray transfer to my partner and numb them?
Yes, it can. If you use a lidocaine-based spray (like Stud 100) and do not wait for it to dry or wash it off, the numbing agent can transfer to your partner, reducing their pleasure. Using a fast-absorbing product like Bombex and wiping off excess residue significantly reduces this risk.
Can I use delay spray with a condom?
Most delay sprays are safe to use with latex condoms, but you must ensure the spray has fully dried first. Oil-based additives in some sprays can weaken latex. Always check the bottle for "condom compatible" labeling. Bombex is designed to be compatible with standard latex condoms.
Will using a delay spray make me lose my erection?
It is possible if you over-apply. Lidocaine is a powerful anesthetic; if you use too much, you can numb the penis to the point where you cannot maintain an erection. This is why we recommend starting with just 1-2 sprays or switching to a non-numbing herbal alternative like Bombex.
Is Promescent better than Stud 100?
In terms of technology and absorption, Promescent is generally considered superior to Stud 100, which reduces transfer to partners. However, Promescent is significantly more expensive per use. Stud 100 is a budget option but requires more care to avoid numbing your partner.
Is delay spray safe to use if my partner is pregnant?
Most medical guidelines suggest avoiding unnecessary chemicals during pregnancy. While lidocaine is generally considered safe, many doctors recommend avoiding active pharmaceutical ingredients in the bedroom during pregnancy to be safe. Always consult your doctor before using any delay product if your partner is pregnant.
Conclusion: The Smartest Buy for Your Bedroom
When you break down the numbers, the battle between Promescent and Stud 100 comes down to a choice between high cost and high numbness. Promescent offers great tech at a premium price, while Stud 100 offers budget-friendly volume with a "numbing tax" on your pleasure.
For us, the real winner is the third option: moving away from anesthetics entirely. The Bombex Phyto Delay Spray For Men offers the perfect middle ground—preserving the natural intimacy of the moment without the medical side effects. It’s an investment in better sex, not just longer sex.
